The rope gearing associated with thelong wall miningmachine 25 may then be operated to cause the cutter 27 to move theblockof material 28 along the platform 31' and upwardly to the platform32 of the mine car, as indi-- cated by the dotted lines shown in Fig. 1;The mine car 32 travels on the track33,

parallel to thefmining machine which is laid track 11.

I Wlll'llOW describe the mlning machine for producingtheyerticalfkerfs2lfland for g shiftingsuch mining machine so'as to move 2 thej sev eredblock of coal rearwardly onto the platform 31. As shown in'Figs. 2, 3and5, this machine is mounted on a truck com prising the wheels 34c and theplatform 35.

platform, there At the central portion or the 7 1s a turntable'COIHPIlSlDg a circular plate 36, having a dependlng cylinder or pivot37,'Which is connected to a ring 38 by means above the platform. Themining'niachine is therefore securely connected to the platform of thetruck, but 'may be moved through an arc of circle by the rope gear ngshown.

' The main frame it? of the mining machine is trunnioned on the circularplate 36 by being secured to the rock shaft ll, which is journaled inthe bearings 42, 42, the attelf being fixed to the peripheral portionsof the disks 86 atdiametrically opposite sides, as'

shown in Figs. and 5.

Keyed to one end of the rock shaft 41 is a segmental worm gear 43, whichmeshes with the vertical. worm 4C4: iournaled 111 the bearings fixed tothe turntable iifi. At the upper end of the shaft of the worm a5 is awheel 46 for manually turning the worm d5. hen the worm 45 is thusactuated, motion is transmitted by means of the worm gear segment as tothe shaft 41, and thence tothe main frame 4L0 of the 'inining inachineQ*Themachine may th refore. be moved 1 to various positionsvertically to effect tertical cuts into'the mine wall atthe desiredelevation.

Anjelectric motor -17 is mounted on the main frame 40 so as to slidelongitudinally on the bottom of the main frame, between the guideways48, 48, as shown in Fig. 6.

The'clectr'ic motor may beprovided with a I'QVGISIHQ switch 49 andarheostat con- .troller 50. To the motor shaft 51 is connected a pinion52, which meshes with the largejgearwh'eel '53. On the outer portion ofthe shaft-5140f the gear wheel 53 is keyed "the sprocket-55, as'shownin'Figs. 5 and'f6. The shaft 54 extends through a bearing 56,

to the frame of. the motor 47.

supported by the bracket extending rear- "wardly from the frame of theelectric wheel-5s, which meshes with the gear 59,

the latter being connected to the sleeve 60,

,i'v 'ch is'lcos'e on the shaft 61 (see 6). the outer side of thebearing 57 is a gear 62, which is keyed to theshaft. 5% and meshes withthe ldler gear (33. -The gear 63 meshes withthe gear (i l, which isprovided with afsleeve mounted in the bearing 66 secured to the frame ofthe motor 47. The sleeve 65 is-mounted loosely on the shaft 61 andisprovided with clutch teeth 67 at its inner end. The sleeve 60 is-alsoprovided Witlrclutch teeth 68 at its inner end. 13etween the clutchteeth 67 and 68 is located a 'clutch member 69, whichis splined to theshaft 61, so as to permit longitudinal movement thereon, butcompelling-the "said clutch member torotate with the shaft 61. Theclutch member 69' is provided with'a circu1n ferential groove engaged bya pin at the end of the lever 70, which is pivoted at 71 A bearing 72extendingrearwardly from the frame of" the motor l7'is provided for theshaft 61, as shown in Fig. 6, andoutside of said 2 bearing is a pinion'73 which is keyedto the shaft 61 and meshes with the rack bar 74, whichis connected at its ends to the heads 75 and of the main frame a0, asshown in Fig. '2.

When the motor is operated in one direction or the other, motion will betransmitted to the gcars52, 53, 58, 59, 62, 63 and 64, but they willrotate freely and no further operation will take place. Whernhowever,the clutch 69 is thrown in, the feeding. mechanism willbe operated ,to'more the cutter head forwardly or rearwardly. the clutch 69 is throwninto engagement with the clutch teeth 68,the pinion 73 will 1 be rotatedin one direction, and if the clutch 69 is thrownin the oppositedirection the rotation oflthe' pinion 73 will be reversed. It will alsobe noted that the gearing is such that the: forward feeding motion ofthecutting mechanism may be carried .on at a slow speed, because of thesmall gear 58 meshing with the larger gear 59, shown in Figs. 2 and 6.The return motion of the cutting mechanism may beaccomplished muchmorequickly because of the large gear 62 being connected to a smallergear-B4.

At the central portion of the shaft 5% is is loosely mounted a worm 77,which meshes with a worm wheel 78. The worm wheel 7 8 is mountedbetween the bearings 79and80,

which are connected the cross-piece 81.

The bearing SO'is supported at the upper end of the bracket 82, which issecured to the rear upper central portioniof the frame of the motor .47.This construction is represented in plan in Fig. 5, and in dotted lineelevation in Fig. 2.

The woringear 78 is provided with a spline or feather that fits into theslot. 83 which extends longitudinally of the shaft 84:.

The latter is journaled at its ends in the bearings 85 and'86,which'aresecuredto the heads 75 and 76 ofthe main frame. Atthe rear endof the shaft 84 is keyed awbevel the worm. 77.

a through the worm 77 and worm gearingv 7 8 gear 87, which'meshes withthe bevel gear 88 keyed to the upper end of the shaft 89.

The shaft 89. is journaled in the vertical bearing90, secured to thehead 76 ofthe" main frame. The lower portion of the shaft 89is journaledin the'bearing- 91, which is fixed to the rear end of the main frame 10.To the lower end of the vertical shaft 89 is keyed the rope drum 92, towhichtwo ropes. are secured at 93 and 9e. The rope 95,-which is securedat 93 to the drunr92, is; wound in one direction, and the rope 96 thatissecured at 94: to. the rope drum 92 is wound in the oppositedirection. The rope 96 is anchored at 97 to'one end of the platform 35,of the, i truck that carries the mining machine, and

the rope 95 is anchored at 98 to'the opposite end jof the platform 35. i

When the; lever 99, shown in Fig. 6 pivoted at 100.to the rearof themotor frame 47,,

is movedjso as to throw in the clutch'101, the shaft 54 will berotatively connected to is operated, motion will be transmitted to theshaft 84 The rotationof this shaft machine will be shifted through anare on the truck by the turntable connection. This operation isparticularly desirableto shift a block ofcoal after beingentirelysevered from the mine wall, over o'nto'the platfornr to aposition indicated by the block. 28 in;

Fig.1,after which the rope gearing a'sso ciated with the mining machine25 maybe relied upon to slide the block of coal over theplatform 31'ontothe minecar 32.

'If it is not desired to, reverse thefmotor by means of the reversingswitch'49 when the mining machine is to be returned to a positionperpendicular-to the mine wall, the modification shown in Fig; 1 will beused, by substituting for-the bevel gears 87 and 88 and their supportsadoublebracket' arm- 102, with bevel gears103, 10%and 1.05, with theclutch between the two latter. The

double bracket arm 102 issecured to the rear end of the main frame 410and comprises bearings106 and 107 for an extended portion of theshaft84, The lower central portion of- When the electric motor side ofthe bracket is the nut 122.

At the upper endof the vertical shaft 89 the horizontal bevel gear 103, which mesheswith both the a bevel gears 104: and 105 on diametrically oppositesides, the latter being mountedloosely v I on the shaft 8 1. Theclutch109 is splined V to the shaft 84 and may be operatedv bymeans ofthe lever 110, which" ispivoted at 111 to the auxiliary bracket arm-112. It

will now be seen that when the clutch 109 is moved to throw in the gear104,-the'rope drum 92 will be operated in one direction,

and iwhen therlutch 109 is thrown in to operate the gear 105, theropedrum 92 will i be operated in the opposite direction. This reversalof the rope drum-92 is thus effected without changing the direction ofrotation of the electric motor.

The frame 113 forthe chain cutter 1141 comprises a longitudinalcentralbar 115,

which is afiixed at its ends to the vertical portions of the said frame,as shown in Fig. 2. The baa-115 1S 1 provided with a slot or opening 116at its inner end into which ex tends a bracket arm 117 from the lateralface of the'niot'or frameti', to which-'it-is Secured, shown" in Fig. 5.EXtending loosely throughan opening in the outer end of the bracket arm117 is a screw-threaded :rod or bolt 118,whieh is rigidly secured at itsinner end to the-block 119, as shown in Figs. 2 and The block1-19 isfirmly fastenedto, the v'erticalbar 120 of the-chain cutter frame; Onone-side of the bracket 117 is located the nut 121, and on the otherloosened and turned back,the nut 122 may be tightened up toa-move theentire chain cutter frame forward, the frame'being sup- By means portedby-the longitudinal bar sliding through the'guidewaysl23 at the outerend of'the bracket 124,- whi'ch is secured to the upper end of the head75 of the main frame ofthe mining machine.

The screu-threaded rod 153 is secured to the bracket 14:9 at 156 so that itcannot-rotateor move longitudinally with respect to the said bracket.Byloosening the nut 154- and tightening up the nut 155; the cutter frame148may; be moved forwardiy to take the slack out of the cutter chain-1-1*'. The nut 155 may then be moved against the bracket 152 to securethe frame 141-8 in ad justed position. and tightening the net 151, theframe 1 1-8 may be movedbackwardly to produce slack in the chain 147, ifitis to be repaired by substituting a new link for-aworn out or injuredone. V a 7 It will be observed that the shaft 116 shown in Figs. 7 and8' is supported by brackets 15Tand 158, which form n ed bearings for thesaid shaft: At the ou'tei-end'of the shaft 11-6" is a gear 159, hicli'meshes with an idler 160 and this in turn meshes with the 161;The-latter is connected to 'a sleeve-162, which is mounted in the lowerportion oft-he bracket-15S and *surrounds the shaft 163. entirelyacrcssthe rear portion ofthe motor 'toasmall pinion 161, which meshesWith the rack 165 on the bar 166 which extends lonof'th'e machine, asshown in Fig. '7.

The bearing 174 is directly secured to the motorframe, and the bearing 175 is secured to the bearing 174 by the crosspiece 17 6, as shown in Figs. 7 and 8. Extending through bearings -174and 17 5 and the worm wheel 173 is a longitudinal shaft 17 7, which isprovided with a longitudinal slot 178, into which extends a spline orfeather from the worm wheel 173, so that the latter may slide along theshaft 17 7. The

end'of the main frame. Between the brack-- ets 188 and 184 is a verticalbearing 187, and between the brackets'185 and 186 is a" vertical bearing188. Between the bearings 181 and 182 is a sleeve.189, which is splinedto the shaft 177 by means of the slot 190 and a feather fitting therein.At the ends of the sleeve 189 are the bevel gears 191 and 192, each ofwhich'may mesh with the horizontal bevel gear 193. Connected to thebevel gear 192 is a grooved collar 194, in. which extends the yoke 195,which is fulcrumed at 196' and provided with aj lever arm. 197. Thefulcrum 196 is supported by'the supplemental bracket l98extending fromthebearing'182j By means of-the ro'd199, which is pivoted 7 at 200 tothe lever arm 197 ,and the lever 201, whichis pivoted tov the main frameand connected at 202'to therod 199, the sleeve 189 maybe shiftedalongthe shaft 177, so as to. bring the bevel gear 191 or the bevel gear192 into 'ine sh with .the bevelgear193. This will provide a means ofreversing the rotation of theshaft 203 whichis keyed to;

actuated in ne direction the bevel gear 191 will mesh with the bevelgear 193 to produce a certain rotation of the rope drums 204 and 205,and that when the lever 201 1s reversed The bearings17 9 and 180 aresupthe bevel gear 192 will mesh with the bevel gear 193 and effect areversal of rotation of the rope drums 204 and 205.

Similar mechanism for effecting reversal of rope drums is shown at theother end of the mining machine. .A lever 206 1s provided with a yoke,the lower ends of which are pivoted at 207 to the bracket 184, as shownin Figs. 7 and 10. The yoke 208 is provided with inwardly extendinglugs210, vhieh fit into acircular groove in the collar 211 which isfixed to the bevel gear 212. Between the latter and the bevel gear 213is a sleeve214, which is splined to the slot 215, and it is thereforefree to slide longitudinally but must rotate with the shaft 177. Thesleeve 214, by means of the lever 206, may be thrust in one direction orthe other to cause the bevel gear 213 or the bevel gear 212 to mesh withthe horizontal bevel gear 215, which is keyed to the upper end of theshaft 216. This shaft extends through the vertical bearing 187 and iskeyed at its lower end tothe rope drums 217 and 218, as shown the drums217 and 218. In this instance, I

have showna lever 219, fulcrumed at 220 to bracket 221 extending fromthe bearing 187, as shown in Fig. 8. A brake shoe 222 is pivoted at228130 the lever 219, and, by

downward pressure on the latter, this brake shoe may be brought intocontact with the to the drum 217, and the other end is an-' choredat 225to the outer upper end of the U-shapedtrack 124. Another rope 226 issecured at one end to the drum 218, and at its other end is anchored at227 to the standard 228, which 1s located at the rear end of the track124. The ropes 224 and226 are wound. on the drums 21'. and 218 inopposite directions, as shown in Fig. 10, so that when the: drum 2 17winds up the rope 224 the drum 218 will pay out the rope 226; and whenthe rope 226 is wound up, the rope 224 will be By means of these ropesand paid out. drums, the truck 125, together with the mining machinethereon, may be positively moved forwardly or rearwardly on the track124. ,By means of the brake 222, shown in Figs. 7 and 8, the miningmachine may be held stationary in any position to which it is moved,particularly when the rear end of the machine is to be held stationarywhile the forward end swlngs aroundand when the mining machine is to bemoved up the inclined portion of the track 124 and loaded onto the truckcomprising the beams 138,

to cut the vertical kerf 26 although usually this will not be necessarysince the wheels 127 shown inFig. 7 engage the rails of the track 124 insuch a manner to resist any tendency of the feeding action of the cutterto move the main frame 126 from its adjusted position on the guidingmechanlsm comprisingthe track 124 andthe-plate 31.

. At theforward portion of the mining machine, a rope is wrapped aroundthe drum 205 and its other end anchored at the rear end of the platform31. at a point indicated by the dot 230 in Fig.1. Another rope 229 iswrapped around the drum 204 audits end anchored at 231 to the forwardedge of the nclined platform31, as shown in Fig. 9. The anchoring of theend of .the rope 229' may be done by means of hooks fitting over t eedges of the platform. It will be seen that whenever the drums 204 and205 are rotated, the :forward portionof the miningmachinewill be shiftedabout its pivot 128.

The operation is such that after the block of coal 28 has been entirelysevered from the mine 'wall and shifted entirely over tor shifts thelever 206 in the proper direc- 131011, and substantially at the sametime operates the lever 201. the drums 217. 218

and the drums 204'and 205 willbe'rotated, so as to move the entiremining machine latera y, which will cause the block of coal 28 to bemoved along'the platform 31 t0ward the track 11. Nhe-nthe truck 125reaches theposition indicated by=the dottedlines 125 in Fig. 1, thelever 206 may bebrought to-central position, so as to stop the continued forward motion of the truck 125 on the track 124, and the brake222 applied to hold it there. The lever 201 may be held in operatingposition, however, which will cause continued operation of the drums 204and 205. and the outer end of the frame ofthe mining machine will movethrough the are 232, shown in Fig. 1, and the outer end of the cutterand the block of coal will describe the are 233. When the block of coalis fully on the platform 31, as indicated in Fig.1,the lever 201 may bebrought to central position to stop the rotation of the drums 204 and205. The lever 201 should then be reversed so as to cause reverse rotaof coal.

to reverse the rotation of the drums 217,

218 and cause the truclc125 to be moved back toward the mine wall. lVhenthe machine is back to its initial position, the mechanism may again befed forward to produce another cut and sever another block W VVheneverdesired, the truck 124 and t-he platform 31, together with the min ingmachine, may be moved forward to a newlocation by moving the truck onthe rails 11, 11, forward. This may be done while themining machine isin the dotted line positionindicated in Fig. 1, or by moving the rearend of the mining machine up the inclined portion of the track 124afterthe block of coal 28 has been moved onto the car platform 32. p thelever 20lcould bemoved to reversing position, so that when the rearportion of the mining machine is being moved up onto the track theforward,portion would be moved baclnvardly and kept froinnioving' offthe outer edge of the platform 31.

The outer end of the track 124 can be lifted when the mining machine isat the upper end of the inclineof the track 124 and then blocks at 140relied upon to hold the inclined portion horizontal temporarily.

Furthermore, if the electric motor 141 is stopped when=the miningmachine reaches the desired position on the truck, and the bevel gear215 1s kept in mesh with one of the bevel gears 212 or 213, the worm 172and the worm gearl'r'linay berelied upon 01001: the drum 217' againstreverse rotation. llhe'mining machine would then be held onthe truck atthe upper inclined por-' tion of the track 124 by the rope 224. In asimilar manner, by keepingthe lever 201 in aposition wherethe bev'elgear 193 is in In such case,

will'thcn keep the forward portion ofthe v mining machine from moving.downtheinclined portion of the platform 31. I

' It should be understood that in the same manner that the inclinedportion of the track 124 may be proppedup at 140 so as to be supportedin a horizontal pi w'tion, the plate 31 may be propped up on the forwardextension of thc beam 138 so that the in clinedportion of the plate 31will. be sup- 1 124 and the plate 31, imn1ediately above the truck. Assoon as the truck reaches the dejacent the base of the upright minewall.

Since thetrack 124 and the plate 31 are pivoted at 132, to the beam 138of the truck which travels on the mine track 13 1, the

track v1241 and plate 81 will adapt themselves to slight irregularitiesof the floor. That is to say, since the track 12t and the plate 31 areindependently pivoted tothe truck, they'may have some relativeflexibility to their downward movement limited by the i ends of the beam138, as shown in Fig. 10.

After the guiding mechanism'comprising the track 121 and the plate 31has been let down to the floor to the desired position, the levers 201and .206, sho-wnin Figs. 7 and 8, maybe so operated as to move the gear191-01 .192 and the gear 212 or 213, respectively, out of mesh with thehorizontal bevel gear 193 and the horizontal gear 215. The miningmachine including the frame126 will then be free to slide down theguiding mechanism by gravity since the worm gear 173 can no longereffect a locking of the rope drums at the end portions ofthe frame126,assuming that the ends of theropes still re main anchored to theends of the track-12 1 and the plate 31 at the pointsi'ndicated in Figs.7 to 10, inclusive. If desired,the motor'latl may be started andthe-rope drums operated in the proper direction to posi tively move themining machine ofi', thetruck down the inclined portions of the track124: and the plate 31 to the horizontal portions thereof so that themining machine will be in, operating position, as shown in Figs. 1

and 10. \Vhen in operating position the" brake 222 may be appliedmanually, but it is preferred to relyon the wheels 127 resting on thetrack 124, to resist anytendency of- .next block of coal'to bereniovcd,the kerfcutter may be retracted to initial position relative tothe frame 126 and the rope: drums operated to move the mining machineback toward the face of the minewall into position for makingthe nextcut.
